I got "Segmentation Fault" when I run my application on another PC without Qt.

[pico]

Hi, Sir:
I follow the way described in "Deploying Qt Applications" to collect all shared libraries into a folder.
And, write a shell script to export LD_LIBRARY_PATH.

@appname=basename $0 | sed s,\.sh$,,
dirname=$PWD/$appname
LD_LIBRARY_PATH=$dirname
echo LD_PATH=
echo $LD_LIBRARY_PATH
export LD_LIBRARY_PATH
$dirname/$appname $*@

And, put my application into the folder as well. However, when I run this application on another PC.
I get "Segmentation Fault"!!

Could you help me to know the reason?? The only library I don't put in is linux-gate.so.1.

Thanks a lot.

BR,
Pico

Well, I don't think that a missing library is a source for segfault. Anyway, you can check if there're some missing libraries using ldd.

I think that your friend can be "strace" or "gdb". So you can give us more informations useful to help you.

I recommend to check the list of linked shared libraries by "ldd -v myapp" on linux and "otool -L MyApp.app/Contents/MacOS/MyApp" on Mac. Then compare these lists on host and distribution system. It maybe some other library which have different version.
